GEARING.

Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed January 24, 1906, Serial No. 297,583. Renewed March 5, 1907. Serial No. 330,762.

' Figure I is a front elevation of a system of gearing provided with my improved cone. Fig. 2 is a longitudinal vertical section of the friction cone. Fig, 3 is a plan view of the larger flange removed. Fig. 4 is a vertical longitudinal section of cone constructed in the usual manner. Fig. 5 a plan view of the removable flange thereof, and Fig. 6 is a perspective view of the sleeve showing thc integral smaller flange.

In the practical application of my invention I provide a sleeve A, having therein a key way a, and adapted to be sccuredto a shaft A, by means of a key a, engaging the key way in the sleeve, and a key way on the shaft. A flange B of relatively small diameter, is formed integral with one end of the sleeve, and is provided with perforations h, for a purpose to be hereinafter described. A series of disks C, of paper or other suitable frictiorrmatcrial, gradually increasing in diameter are arranged on .the sleeve, and secured in place by a ring or flange D of relatively large diameter.

The flange or ring D is provided with a central opening for receiving the sleeve, and is retained in place upon the sleeve by a double gib or yoke key (I engaging a key way d in the flange, and a key way a on the outer surface of the sleeve.

A series of bolts E, four in number, inthe present instance, traverse the perforations in the smallerflange, alined perforations in the friction disk. and perforations in the larger flange, and are engaged by nuts 2 on the face of the larger flange.

In Fig. l of the drawing is illustrated a system of gearing containing friction cones of my construction. In this figure, a vertical shalt F is provided at its lower end with a cone-faced wheel (,1 and a horizontal shaft A secured therebelow, supports the friction cone for engagement by the cone-faced wheel.

In Fig. 3 is illustrated the friction cone as heretofore constructed, comprising a sleeve H, having intcgral with one end thereof a flange of rclativcl y large diam fact I, and removably secured to the inner end a flange J, of relatively small diameter. The friction disks arc arranged between the flanges upon the sleeve and the removable parts secured by the bolts and nuts K.

In refilling the above described construction of cone, it is necessary to remove the supporting shaft from its bearings, the key attaching the sleeve to the shaft must be taken out, and all the parts including the slum u removed from the shaft. The smaller inside flange .is itself removed from the sleeve by loosening the ,transverse bolts, and the friction papers or disks removed one by one, which is a very diflicult operation. The worn or useless disks are-culled out and'replaced by then re-assembled and the shaft returned to its bearings. Much time is required for this operation, it in ordinary cases requiring the services of two millwrights for approximately four hours, and in addition there is'much wasted material, many of the disks being destroyed in removing them from the sleeve.

In refilling a friction cone of my construction it is" only necessary to elevate one end of the shaft from its bearings, remove it to one side of its hanger, and loosen the transverse bolts'to slacken up the filling material. With a cold chisel worn or useless disks are cutaway from the inside end of the coneand the remaining washers are shoved in against the inner'flange. Enough disks are then put upon the sleeve to replace these removed, the large flange is secured in place, and the shaft is returned to its bearings. Two mill-Wrights can refill the Worn cone of my construction in about one hour, and only the worn disks are destroyed.

It will be evident from the above that much time, labor and consequent expense is saved by the use of my improved cone, and that it will rarely be necessary to shut down the machinery for any considerable length of time on account of worn cones. I

In Fig. l, I have shown a mechanism whereby to wear. In this construction, a collar M. provided with a setscrew m whereby it may be lined with respect to the shaft, is connected to the smaller disk R. by means of the screw threaded rods m, secured to the CllelI, and traversing openings in the collar. Lock nuts m are arranged upon the screw thrcadedrod upon each side of the collar, whereby to secure the cone in itsadjusted position.

- The collar may be of any desired construction, and after being placed on the shaft in proper position is fixed thereto by means of the set screw. When the cone becomes worn the lock nuts are loosened and the cone is adjusted, after which the lock nuts are again tightened. i I Having thus described my invention, what I claim as new and desire to secureby Letters Patent is 1. In a friction cone gearing, the combination of the vertical shaft, :1 (zone faced when] secured to the shaft, :1 horizmrful shaft journalcd below the vertical shaft, a friction cone on the shaft and engaging the cone shapcdface of the wheel, and comprising a sleeve mounted on the shaft, a key for securing the sleeve to the shaft, :1 flange of relatively vsmall diameter integral with the sleeve at the inner end. a flange of relatively large diameter on the outer end of they sleeve, a yoke key engaging the flange and sleeve, friction disks or gradually increasing diameter new disks enough to refill the cone. The parts are easily adjust the cone on the shaft to compensate for from within outward on the sleeve between the flanges,

flanges, and nuts on the outer face of the larger flange for engaging the bolts to secure the disks and flanges together.

2. in a friction cone'gearing, the combination of a vertical shaft, a cone shaped wheel secured to the shaft, a horizontal shaft journaled below the vertical'shaft, a friction cone on the shaft and engaging the cone shaped face of the wheel, and comprising a. sleeve mounted on the shaft,

\ means for releasably securing the sleeve to the shaft, 21

flange of relatively small diameter integral with the sleeve at one end, a flange of relatively large diameter on the sleeve at its other end, means for securing the flange to the sleeve, friction disks on the sleeve between the flanges, and means for securing the friction disks and the flanges together. Y 3. in a friction conegearing, the combination of-the vertical shaft, a cone faced wheel sect red to th shaft, :1 horizontal shaft journnlcd below the vertical shaft, a friction (zone on the shaft and engaging the cone shaped face of the wheel, and comprisil'ig a sleeve arranged on the shaft,

means for securing the sleeve to the shaft, a flange of relatively small diameter secured to the sleeve at its inner end, a flange of relatively large diameter removably secured to the outer end of the sleeve, friction disks on the sleeve between the flanges, and means for securing the disks and flanges together.

4. in a friction cone gearing, the combination of the vertical shaft, a cone faced wheel secured to the shaft, a horizontal shaft journalcd below the vertical shaft, a friction cone on the shaft engaging the cone shaped face of the wheel, and comprising a sleeve mounted-on the shaft, a flange of relatively small diameter rigidwith the inner end of the sleeve, a flange of relatively large diam: fer releasably secured to the outer end of the sleeve, friction disks on the sleeve between the flanges, and means for securing, the flanges and disks together.

5. In a friction cone, the combination of a sleeve having an inner flange of relatively small diameter integral therewith, a flange of relatively large diameter movable thereon, and means for securing the flange to the sleeve comprising a yoke key seated in a groove on the sleeve, and having its arms embracing the faces of the flange.

6. A friction cone, comprising a sleeve having thereon a. movable outer flange, and means for securing the flange to the sleeve comprising a doublegib key resting in a groove on the sleeve, and embracing the faces of the flange.
